JEMOUNTABLE RIM.

Application tiled .Tune 4,

To all 1c/umani may concern.'

Be it known that `l` BENJMHN F. (iownn, a citizen `of the United States'. residing at Englewood. -in the county of Bergen :ind State of New Jersey. have invented new and useful Improvements in Demountahle Rims, of which the following is a specification.

This invention relates to demountable rims and particularly to such structures as shown in my prior Patent No. 1,318,274, granted October 7th. 1919; and the principal ohject is to provide additional and positive locking means for preventing creepingr of thc demountahle rim on the telly.

Another object is to provide a rim of this nature with a dependingr flange for concealimer the mechanism which locks the rim and telly together.

lVith the above and other objects in view which Will appear as the nature of the iurention is hotter understorul. the salue consists in the improved const ruction and novel arrangements of pa rts which will hereinaft er he fully deserihed and pmticularl)7 pointed out in the claim.

Figure 2 is a transverse section through :i portion ol' the wheel and rim.

Figure 3 is a plan view oi' a port-ion of the fixed rim.

Figure 4 is a plan view of a portion ot the (lemountahle rim.

Figure 5 is a bushing. Y

Figure 8 isa transverse section taken suhstantially on line 8-8 of Figurey l.

Figure 9 is a tra,qr1"ientar iY view of a portion of the inner surface of the rim showingr in detail the locking` block.

The. demountehle rim structure comprises a depionntahle rim l0 adapted to he connected in a suitable well known manner with the shoe ll and a fixed rim l2, the latter being connected in :my suitable well known manner with the telly 13 of the perspective View of fthe 1921. Serial Ho. 474,872.

wheel. The mentioned rim 12 is provided at one side with a Bange 14which is adapted to he rejected against one side of the demounta le rim when the latter is properly applied as illustrated in Figure 2. o

The demountahle rim is provided with wedgclike projections 15 which are adapted to co-aet with similar projections 16 0n the fixed rim, These projections are adapted to lie one beside the other and when the rim is turnedthey operate to cause the same to he moved in the direction of the flange 14 of the fixed rim. Other wedges a-rc formed as integral projections of hoth rims and are respectively illustrated at li' and 1S. They are adapted to lie in superposed relation and are arranged whereh) to cstahlish a secure connection hetween both rims, ln this manner. the demountable rim is laterali)Y adjustable and also circumferentiallj' adiustahle.

ln order to fixedlj' position and retain the lelnouutahle rim on the fixed rim, use is made of a hushing 1.9 which err-tends through the fellv of the wheel. Against the inner face of the tell)1 and forming a fixed part of the bushing is a locking ange El) having' from-rs El which radiate from the center of said hnshiniIr as illustrated in l"i;:ure 5. to Frech rotate therein is a stern 22 which is positioned heronil the rim IQ Where it is provided with z: crescent shaped head 23 whose conrexitr Qi is adapted to be pro. iecterl into a receiving' concarity 25 in n tizxetl crescent shaped projection 26 on the.

demountahle rim l0. W'hen the parts are positioned in this* manner. it will he ohserveil that the demountahle rim is held against retrograde rotation on the. fixed rim.

fn order to prevent the stem Q2 from caswally revolving in its bushing` use is made of the mentioned flange. and as shown the stem is provided with a locking washer 27 having radio1 rihs 28 adapted to Ht. in a corresponding number of grooves 21 in said flange 20. The free terminal of the stem is provided with angularl)7 disposed surfaces 29. while at a point immediately adjacent said surfaces the stem' threaded as at 30 where it receives an adjustingr nut 3l. This nut is ada ted to comey against the washer 27 and adi ance the same into eo-aetingr engagement with the mentioned flange 20. Through this arrangement of instrumentalillrtending through and adapted los ` ties. the stem is Vpositively held in fixed position. The dernountable rim is also held ixedly connected against the fixed rim.

All of the parts mentioned above are disclosed in my said former patent so far as above described. While these devices have proven eifecive, in certain classes of wheels, 1t ha's been ound that the parts would tend to loosen and permit a creeping of the rim on the felly. The present invention now to be described relates to means for positively locking the felly and rim against relative movemenbend to means for covering the working parts so as to proltect them and give the entire wheel a more attractive appearance.

Referring again to the dra'wing, and particularly to F1 ures l, 8 and 9,'l a nut 35 is seated in the fe ly 13 abutting the rim 12` A bushing 36 extends through the felly from the inner surface of the felly. A bolt 37 extends through the bushing 36 and threadedly engages nut 35. The outer end of the holt 3T passes throu h the rim 12 and is rovided with a"`curve outer end 38 Whici is adapted to seat itself in la curved seat 39 formed in the inner face of a plate 4() secured in any suitable manner to the demountable rim 10. Bolt 3T is formed at its inner exposed end with a manipulating ortion 4l to which a wrench may be agp lie for forcing the bolt throughnut the end 38 into firm contact Withat 39. A lock nut 42 is screh'ed onto the inner ortion of bolt 37 and against the inner sur ace `ot' the felly and against bushing 36, therby locking bolt 37 against turning and h Ading the bushing firmly seated.

The demountable rini 10 is formed with a vertically extending Han e 43 which with the flange ,14 previously escribed entirely conceals the various parts located between thc rims 10 and 12, and protects them from injury.

While I have dcscribed'lny improvements as applied to the structure shown in my said former patent, it is to be understood that the present invention is not limited to use with that precise form of wheel, but is applicable to various other forms of construction.

What I claim is 1. In a vehicle Wheel, a wheel rim, a demountable tire supporting rim, means on the wheel 'rim and means on the demountable tire supportin l'n-st mention@ means, for shifting the deinountable tire supporting rim with respect to the wheel rim in a"lateral direction and for preventing the demonntable tire supporting rini from rotating with respect to said wheel rim, and means for locking the two rims together, said means comprising a bushing mounted in the felly of a wheel, a nut seated in said felly adjacent said bushing, a bolt having threads thereon for coaction with said nut, a locking nut Secured to the inside portion of the bolt, a recessed plate formed on said tire supporting rim for the reception of one end of said bolt for locking engagement therewith.

2. In a vehicle wheel, a wheel rim, a deinountahle tire supporting rim spaced from said wheel rim, means on the wheel rim and means on, thedemountable tire supporting rim which eo-act with the first mentioned means, for shifting the demountable tire supporting rim with respect to the wheel rim in a lateral direction and for preventing the delnountable tire supporting rim from rotating with respect to said wheel rim, and means for locking the two rims together, said last means comprising a recessed plate on the delnonntahle tire supporting rim and a locking clement having a portion thereof engagealilc in the recess of said plate, said locking elmneni being carried by said wheel rim, and an annular .lange formed on each of said rims on opposite sides for closing the space het Ween the same.

ln testimony whereof l have affixed my signature.
